+# GetSfiK
+
+This Powershell script retrieves current Solor Flux Index and K Index information in JSON format from NOAA. It then returns the two most current variables (SFI first and K-Index second).
+
+Only really useful to amateur radio operators looking to quickly evaluate HF propagation conditions from a PS command line.
